WANs

I roto i te whatunga rorohiko ki te whakarite ngā taumata hototahi o paerewa motuhake e whakamahia ana e te hoahoanga whatunga, ka karanga tikanga. haere mai ratou i roto i te taputapu me te pūmanawa. E tautokona pūrere pūmārō (atanga) i runga i te paerewa paparanga tinana, a ka mahi ratou i te raraunga ki te tautoko pūmanawa motuhake.

E tautuhia e te mea kawa whakamahi ratou Ngā LAN i me WANs. Ko te rorohiko whatunga e te nuinga whakamahia hoki te huinga kotahi o paerewa kötuitui ngā kaiuru katoa, me te hono rorohiko whare, whare, papa.

hipokina WANs, rite ki te tikanga, ngā wāhi nui. ngā ratou e rua rorohiko takitahi me whatunga rohe rohe whakamahi ngā kawa.

Ko te mahi o te hapori ritenga i roto i ngā āhuatanga hou e taea kahore tikanga o kōrero tere, me te whakawhitiwhiti tere o te mōhiohio. E hangaia WANs ki te whakatutuki i tenei raruraru. Ko te huru taketake mo te mahi o enei whatunga ko te inamata tuku o ngā mōhiohio , ahakoa o pehea e nekehia rorohiko i ia atu.

whatunga Global - ko te whatunga taua, e ngā rorohiko, kei roto i te whenua nui mo te here i te maha o ngā pūnaha rorohiko hono ki te whatunga tenei. Ko te auau raraunga ko raro atu i te rohe i roto i te whatunga.

kawa whatunga rorohiko

tautoko whatunga ao te TCP / IP, ATM, MPLS, me ētahi atu. Ko te kawa tino noa - he TCP / IP, tae atu i te iti-kawa. Reira - tono subprotocol, waka, whatunga, hono me te tinana.

mahi te nuinga hōtaka i te taumata tono me te whai ratou ake tikanga. Reira - HTTP, WWW, me ētahi atu He kawenga mō te tāhuahua me te whakaatu i te mōhiohio e hiahiatia ana Kawa.

kawa Transport fakapapau'i tuku raraunga o tono motuhake e taea te hapai i ratou. huaina TCP te.

kawa Whatunga IP he kawenga mō te fariiraa i me te unga tono ki te taumata o raro ki te tiki i te kōrero e tika ana katoa.

Hongere me kahu tinana te kawenga mō te whakatau i te tikanga me raraunga tikanga tuku.

Kia mohiotia whatunga ao: mo te tauira, WWW (WorldWide Tukutuku). Kei te whatunga o tūmau e rokiroki i te mōhiohio e tika ana mō ngā kaiwhakamahi me rorohiko takitahi e riro mōhiohio i te tūmau, me te uta i te reira ki a ratou. WWW Network - watea, me te ngāwari ki te whakamahi.

whatunga ao ngā subnetwork arā, o ngā wāhanga motuhake pērā i ngā rārangi kōrero me ngā huānga whakawhitinga. Ko te rārangi o te kōrero te kore e mohiotia ana ko takere huarahi ranei, i runga i a ratou, Kei te oho raraunga i mīhini ki mīhini.

Whakawhiti huānga e kua whakamahia ki te hono rārangi kōrero, te mahi rite pouara. Te reira - motuhake rorohiko.

WANs te tikanga he maha nui o ngā rārangi waea me taura e hono te rua o pouara roto i.

He taea tuarua ki hono i waenganui i te pouara ko te hononga reo irirangi, te whakamahi i amiorangi repeaters whenua ranei. Ia pouara he ona ake pūihi, ai ko reira e taea ki te farii i me te unga tohu. Ka taea te ngāwari tangohia pouara Whatunga i te tohu amiorangi, a i roto i ētahi wā, i ratou te whai wāhi ki te whakarongo ki te kōrero tuku i roto i nga pouara tata e tonoa e raraunga ki te amiorangi. I roto i te tahi mau WANs, tuati-pouara katoa noa whatu e rua-ira, he amiorangi whakaratohia ki etahi anake o ratou. E päpäho whatunga amiorangi me he te nuinga i roto i te tono nga wahi katoa e tika ana ki te whakarite i te haapurororaa.
